Blue Credit

A Blue Credit is a type of Bonus Credit that is blue in color found in Metroid Prime 3: Corruption. They can be obtained by scanning pieces of Lore found throughout the game or by saving three Federation Marines on the G.F.S. Olympus. There is a limited number of 52 credits that can be found (the first 48 come from scanning Lore, and the last four come from saving the Marines).

Ten Blue Credits in two groups of five can also be obtained in the Special Mission flash game. Each credit comes with a number and riddle that must be solved to form a five digit Access Code, which can be entered into a Key Code terminal to unlock a wallpaper.

Blue Credits can be used to purchase bonus items in the Extras Menu.You can acquire Blue Credits by locating and scanning Lore spread across the different worlds. Completing special goals will also reward you with a Blue Credit.
